The brake shoes can be inspected without removing the brake drum if necessary. Remove the inspection hole plug in the backing plate. Check the shoe lining thickness through the hole. If they are less than the minimum of 0.039 in. (1.0mm), replace the shoes.

REMOVAL & INSTALLATION



Drum brakes require the use of two common brake tools to make the job easier. A brake spring wrench and a spring removing tool can be purchased at almost any automotive outlet for low cost. These are two of the handiest special tools you can own; they can generally be used on any vehicle with drum brakes.
